Application filed September ie-1922. Ssiafiit'of 6611975.

folded papers in up-right fiat en gement onewith "the other, and will effectivelyf-prevc11t'fdldin'gor rumpling of'the papers, and also to provided a novel form of receiver structure for receiving the "folded papers which embodies a suitable supportmovable in a-step by step movement upOn'the-Tec'eiv ing ofe'a'ch individual paper.

Another'object-of'this invention is to prol'aositively, accurately and nicely feeding the paper tothe fin'alfolding rolls.

The present invention I embodies a folding anddischargi-ng mechanism particularly applicable "for use upon napkin folding machines as disclosed in the applicationsfiled April "4;. 1922, Serial No. 549,534: and Sep ".ten'iber'22 1922, "Serial No. 589,834 and 'it also embodies improvements *ov'erf the discharging mechanism for paper foldi'n'gmachines as 'disclo'sedinour companion application tiled lilay 4, 1923, Serial No. 636,613. Other objects of theinventionWill appear in the following detailed description taken in connection with-theaccompanying drawi u gs wherein -r 1 r Fig. 1 isa vertical'section through a part (it a paper folding machine illustratin gt-he present invention.

Referring. more particularly to the drawings; the improved discharging mechanism is associated With a napkin or paper folding machine as disclosed in the applications above mentioned which machine includes a' pair of cutting members 1 which cuts the paper into proper lengths. As disclosed in the said mentioned patent applications the ting and a' fter it has finfal fielding roller 3 which is 'theshaft "'e. The "shaft 4 is suitable manner; from a the folding rollers -1 and "mounted about the eccentric -21. centric 21 is in turn mounted upon the-shaft after it has be'en cut.

paper is folded longitudinally, prior to cutbe'en cut by the knives 2, on the Tellers 1 it is iolded tr'ansve'r'sely orgivpn the finalfold bypass'ing 'it between one o the knife carryin'g rollers'l and a mounted upon driven in suitable power source which, 11owevei-,=fonns no "partdf the present application but is "embodied :in the entire machine structure. The cutpaperfis 's ghtly bent intermediate its ends and guided to the proper folding position 'bet'ween 15; carried'by anil critendstransversely frcm vide m'ean's, ina paper folding machine for lower end of the'suppoiting bar6isattaclied to the forward end of a rack T, which "rack asuitable carrying ors upporting bar '6. The

has transversely "extending guiding ribs 8 formed longitudlnally "along its edges which u pona 'shaft 12.- The structure 10 thereon, the-teeth otwhic h mesh with the teeth 14 on a second rack 15. The rack 15 is 'slidably supported by 'suitable guides 16 formed on "the housing '10 and it has an upstanding-"ear 17 formedthereonto which an eccentric 'rod '18 is pivotally connected as shown at 19. The eccentric rod '18 is connected to an eccentric band 20 which is The cc- 4 so that 'upon rotation of the shaft 4 the rack 7 and consequently the feeding bar are moved towards or from "the *ro'llers 1 The paper feeding inoven'ieiit' of the feedingbar towards the roll'ers 1 and 3 is regulated by 't he action of the eccentric 21so as to properly feed the paper to thejrollers 'The :paper which is fed to the rollers land 3 is folded or c'reased transversely and 'upon issuing from between the "folding rollers is guided downwardly by anendleSsbelt-QQ which travelsover suitable guiding roilers 23 and '24. The roller 231 has a gear 25 thereon which meshes with the gear 26 on the shaft 4. The roller 3 is provided with circumferential grooves 27 into.

which tongues 28 formed on the guiding plate 29 engage so as to prevent the folded paper from getting beneath the guiding plate 29 or being moved downwardly below the horizontal axis of the roller 3. The plate 29 cooperates with the endless belt or conveyor 22, in delivering the properly folded paper into the receiving trough 30.

A follower structure such as disclosed in the patent application upon discharging mechanism for paper folding machine, filed May 4, 1923, Serial No. 686,613 may be provided for moving the individual folded and by an arm 38. The arm 38 is pivotally connected as shown at 39 to the operating arm 40, which arm is in turn pivotally connected to the slide 41 which supports the follower 31. The slide 41 is operated from the shaft 4 through the medium of an eccentric 42 and an eccentric rod 43, as clearly shown in Fig. 5 of the drawings. Upon each forward movement of the slide 41, such movement being timed to coincide with the delivery of the complete folded paper to the trough, the arm 38 will be rocked to.

rotate the ratchet 36 one step movement through the medium of the pawl 37 which will move the upper run 33 of the conveyor 32 forwardly one step and feed the last delivered paper outwardly out of the path of the succeeding folded paper delivered to the trough thereby preventing confusion in the assembling of the folded papers in the trough and insuring proper and free feeding of the folded papers or napkins through the trough.

In Fig. 4 of the drawings two of the racks 7 are shown, it being understood that such construction is adapted for use in a battery or double folding machine structure and it is also to be understood that tne other parts of the machine illustrated and not specifically described in the present application form a part of the machine as disclosed in the above mentioned applications for Letters Patent.

It is, of course, to be understood that the invention may be constructed in other man- 11ers and the parts associated in different relations and, therefore, we do not desire to be limited in any manner except as set forth'in the claims hereunto appended.

upon Having thus described our invention what we claim is:

1. In a paper folding and cutting machine, a pair of final folding rollers, a feed bar for feeding the paper between said rollers, a slidable rack, means connecting said slidable rack and feed bar for moving the feed bar into and out of feeding position movement of the rack, a second slidable rack having means connected therewith for pressing the front portion of the stack, an eccentric driving connection with said second slidable rack, and means connecting the first and second racks for driving the first rack upon movement of the second named rack.

2. In a paper folding and cutting machine, a pair of final folding rollers, a feeding bar for feeding the paper between said rollers, one of said rollers being provided with annular grooves, a guide plate, tongues on said guide plate and engaging in said grooves, an endless belt cooperating with said roller and guide plate in the discharging of folded papers from the folding rollers, a receiving trough for receiving the folded papers from said guiding plate, and a movable conveyor within said trough.

3. In a paper folding and cutting machine, a pair of final folding rollers, a feeding bar for feeding the paper between said rollers, one of said rollers being provided with annular grooves, a guide plate, tongues on said guide plate and engaging in said grooves, an endless belt cooperating with said roller and guide plate in the discharging of folded papers from the folding rollers, a receiving trough for receiving the folded papers from said guiding plate, a movable conveyor within said trough, and means for moving said conveyor in a step by step movement one step upon the delivery of each folded paper to said trough.

In a paper folding and cutting machine, a pair of final folding rollers, means for feeding the paper between the said roller, a slidable rack, means for connecting said slidable rack to the feeding means for moving the feeding means into and out of feeding position upon movement of the rack, a second movable raclr connected to a follower structure member and means con necting the first and second racks for driving the first rack upon movement of the second named rack.

In testimony whereof we afiix our signatures.
